Application filed August 22, 1908. Serial No. 4 59,75 0.

T 0 all whom it may concern:

Be itknown that I, JOHN VVUNDRAOH, a citizen of the United States, residing at Chicago, in the county of Cook and'State of Illinois, have invented certain new and useful Improvements in Sausage-Machines, of which the following is a specification.

My invention relates to certain new and useful improvements in a machine for filling cases with sausage-meat, and pertains more particularly to a friction drive mechanism and certain other features hereinafter described and claimed whereby the efliciency of the machine is greatly increased.

While the invention is intended primarily for use with power stuffing machines, the same may be applied to a hand stuffing machine with equal facility and with little or no modification of the salient features.

In the accompanying drawings forming part of this specification and in which similar. reference characters indicate like parts in the several views :Figure 1 is side elevation of a power stufling machine embodying my invention. Fig. 2 is a vertical cross sectional view partly broken away. Fig. 3 is a cross sectional view on the line 33 of Fig. 1. Fig. 4 is a detail of the lever It and brake-roller T.

In carrying out my invention I provide a suitable table or support, A, upon which the mechanism is appropriately secured to opcrate as hereinafter indicated. To this table is bolted or otherwise secured the parallel vertically disposed sides B which constitute a rigid frame for the proper mounting of the operating mechanism, said sides, B, being formed or provided with journal boxes or bearings, C, for a horizontal shaft D, which extends transversely across one end of the machine. This shaft is, by preference, a power-shaft and is provided with fast-andloose pulleys E, E, of the usual form and which are designed to be run by a belt not shown, driven from some source of power. In the shaft D between two of the sides B, is fixed a friction-drive wheel F, which is constantly driven by said shaft. The opposite end of the frame formed by the sides is also provided with journal-boxes or bearings for a horizontal transversely-extending shaft, G, on which between two of the aforesaid sides, B, is mounted a frictionwheel, H, which is adapted and designed to be driven by the shaft D and its frictiondrive wheel, F, through the medium of an intermediate idler friction-pulley, I, which latter may be shifted vertically from one po sition to another, when desired to connect and disconnect the driven frictionwheel, H, with the driving friction wheel, F, before described. In order to effect this latter resuit, I construct two of the side frames with vertical guides or channels, J, in which are slidably-mounted the side members of a Vertical frame K, said frame having suitable bearings for the ournal ends of a horizontal transverse shaft, L, carrying the aforesaid idle friction-pulley, I, said pulley, I, being located intermediate of the driving and drivenpulleys and adapted to be manually lowered to bring its periphery into frictional engagement with the peripheries of the driving and driven-pulleys, and to thereby transmit motion to the latter, and to be automatically raised, when desired, to remove its periphery from frictional engagement with the driving and driven-pulleys and thereby disconnect the driven-pulley from the power.

The means for operating the frame which carries the power-transmitting pulley, are herein shown as consisting of a lever, N, under the table, A, having one end pivoted, at a, and having the opposite end attached in some suitable manner with a connection, 6, which is operated, when desired, through the medium of a foot-lever, 5, within the control of the operator.

The return of the frame and its powertransmitting pulley from a depressed to an inoperative elevated position, may be effected by any well known elevating means, for instance by suitable springs, 0, upon which the slidable frame is supported, said frame carrying a rod or connection, 0, engaged by a yoke, cl, which in turn is connected to the lever, N. The yoke may have the same function as the usual turn-buckle, for the purpose of regulating the tension of the springs and throw or length of movement of the slidable frame.

The meat cylinder, P, is located in advance of the driving devices heretofore mentioned and has trunnions, e, on its side near the front or delivery end and seating in bearings in a frame or support, f, whereby the cylinder may be tilted in a vertical plane in a manner and for a purpose well known in this art.

The front end of the cylinder has the usual tapered nozzle, P, over which the case is slipped; and the rear end of the cylinder is open to receive the charge of meat and to operatively admit the usual plunger or follower, g, which has the usual rearwardly-extending rod or stem, h, with a rack, 2', adapted to be engaged by a pinion, j, on the shaft, 70, whereby the forward feeding and reversing or withdrawal movements are imparted to the plunger.

In order to obtain a quick reverse movement of the plunger, I construct the shaft, G, of the driven pulley, H, for a transversely-sliding movement, which may be effected by the usual key and key-way conmotion between the shaft and pulley; to facilitate this action the shaft may be provided with a handle or handhold, 3, on one end, as shown in Fig. 3. The opposite end of this slidable shaft is provided with a pinion 10 which when the plunger is operating to compress the meat in the cylinder, is in mesh with a large gear-wheel 11 on the same shaft, is, which carries the pinion, j, which engages the rack, i, said shaft having also a pinion, 8, fixed to it and maintained in mesh with a large gear wheel, 12, on a counter-shaft, 13. When these gears are in the position shown in Fig. 3, the plunger is operated by a relatively slow movement through the pinion, 10, gear wheel 11 and rack and pinion; when the sliding shaft is moved transversely, the pinion, 10, thereon is brought into mesh with the large gear wheel, 12, on the shaft, 13, and through this gear and they pinion, '8, and the rack-andpinion, the plunger is given a quick-return movement, which is desirable when the cylinder requires refilling,

The position of the slidable shaft may be maintained in either of its two positions by means of a latch, 14, or other well known appropriate means.

Beneath the table, A, of the machine and extending transversely and having one end pivotally connected to the stationary support, is a lever, B, having a bracketor bearing, S, for a small friction-roller, T, which is adapted to bear against the periphery of the driven friction-pulley, H, and to serve as a brake for checking the backlash or rearward movement of said driven-wheel. A sprihg plate, 6, whose tension may be adjustable by means of a set-screw, 7 is adapted to serve as ah effective brake-shoe for the roller by pressing against the same with the requisite pressure. g

It will 'beunderstood that the tendency of the driven friction-Wheel is to run backward under the influence of the pressure of the plunger g, which is connected with said driven-wheel through the rack-and-pinion construction before described, during the interval after the operator has one casing filled and is placing another casing on the discharge nozzle of the meat cylinder, and backward movement of the driven-pulley would require several revolutions of the pulley in order to bring the plunger back to its former position. The object of the brake-roller is to prevent this rearward movement of the driven-pulley and to thereby hold the plunger in its proper relative position in the cylinder, during the release of the power from the driven-pulley, and the removal of one casing and the inser tion of another. The brake-roller is brought into operation substantially coordinately with the elevation of the transmitting friction wheel, I, from its engagement with the driving and driven pulleys, and to this end, the lever which carries the brake-roller is connected by a rod, 7, or other means with the lever, N, which controls the vertical movement of the power-transmitting friction-wheel.

hen the operator releases the pressure upon the foot-lever 5, suitable springs, s, 8, act to return the lever, N, to normal position and to lift the brake-roller into contact with the driven friction-wheel, this action occurring coerdinately with the elevation of the transmitting friction-wheel and the removal of power from the driven-wheel.

lVhile the friction-wheels may be of any suitable construction, I prefer to make them of compressed fiber inclosed between two metallic side plates, 15, as shown. I also prefer to attach to the plunger rack, 2', a safety device 16, which is designed to engage with a lever, 17, when the piston reaches the lower extremity of the meat cylinder, said bell-crank engaging with the foot-lever, 5, through the medium of a chain or other connection, and being arranged to prevent the plunger entering too far into the cylinder.
